Avionics Panel

Posted on July 23, 2015 at 11:16am 4 Comments

I have began installation of the Advanced Flight Systems Inc. avionics panel in my 601XLB.  It contains mostly Dynon equipment.  I would surely appreciate any and all input on successful placement of the remote boxes that attach.  E.g., ADAHRS, ELT, remote magnetic compass, etc.…


Brake Line Routing

Posted on June 18, 2012 at 12:27pm 4 Comments

I find the plans and photos just a little short when it comes to brake line routhing.  I have brakes on left only.  If anyone is really happy with their routing or alternately if anyone would like to share "how not to route brake lines" I would certainly appreciate it.

Jabiru 3300A Controls

Posted on August 26, 2011 at 9:29am 8 Comments

I am in the process of odering a plug n play instrument panel.  I cannot decide whether to put engine controls in a quadrant attached to fuselage or the more standard push-pull controls in the panel.  I don't even know right now how many controls are needed.  Throttle for sure but I would assume no mixture since it has an altitude compensated carb.  How about choke?  Is carb heat needed on the Jabiru 3300A?  Any suggestions or lessons learned sure will be appreciated. I hope to have two of each… Continue

Dynon Autopilot Servo Installation for 601XL with single stick

Posted on August 18, 2010 at 10:48am 6 Comments

Does anyone have some photos or drawings or what have you of a successful pitch and roll servo installation. I am near the point of starting that and would love to have some really good ideas to consider and possibly steal. I hate re-inventing the wheel. Takes away too much time for real inventions. :-)

Thanks Joe. I went ahead and ordered a new steering rod from Zenith. It was only $16 and change with the various hardware. Once I have it off, I'll post a picture. Basically, the bent steering rod made it so that the left and right rudder pedals weren't even when the plane was taxiing straight. This would make for a tricky landing, especially if side slipping, so I decided to just replace the part.

Hi Joe

I have done Zenith paper transferr work for my Ch650B now  so hope to get updates soon.

Reading your Kitlog section re: canopy hoop problems.  I have exactly the same problems.  I have been wrestling with this for 3 months.  This &^%$#@! thing is making me suicidal.  How did you finally resolve yours?

Joe: I did run both cables through the firewall. The knob ends are located just under the panel at the extreme left and right sides of the cockpit. The carburetor ends terminate in Heim bearings that are bolted with a long AN bolt and spacer to the throttle arm. I am considering making a change to bolt each bearing to a separate hole to get rid of the long bolt, but this would change the "throw" length of one of the cables, so this change is still in the "thinking about it" stege. I do understand your desire to keep the firewall with as few holes as possible.

Joe: Since my engine is a Continental, I was concerned only with the throttle. I believe that the mixture located in the center would be no problem and of course I have no choke. I ran two flexible cables salvaged from a Cessna with an extended attach point on the carburetor throttle arm. The pilot's side cable can be locked for cruise stability, but I removed the locking feature from the co-pilots side. The plane has not yet flown, but the system works easily and well.

Looks like you are about in the same position I was a year or two ago when the rebuild order came down.  I was asking questions about the Dynon autopilot installation and working on my canopy.  I haven't finished any of those things.  And just getting started on my rebuild.  But I am getting fired back up again.  Got one wing out of the rack and removed the top and nose skins yesterday.  Going out to start on the main spar reinforcement today.  My big question is, should I bother with primer paint on these parts, or just hurry up and install them bare, no paint.  All my other parts are primed on the contact surfaces.

Joe, The positioning should not pose any elevator travel issues. You can experiment by clecoing the the attach pieces to the fuselage and fitting the HS with clamps. Put the HS full forward and then as far a ft as edge spacing will allow and see if there are any elevator travel problems with either placement.

Joe, I tried to reply to your forum question, but it would not let me post it..issues with my laptop combined with being on an overseas business trip, I suspect.  I will try to leave it to you directly on your comment wall-------->


Just my opinion of the Zenith design tennants combined with over simplified logic skils (with some humor mixed in):

HS fore and aft positioning is defined by:  A+B+C=D


A=The HS cannot be mounted any further forward that that aft fuselage bulkhead.

B=The HS cannot be mounted much more that an inch or so aft of that bulkhead with out starting to violate the edge distances on the HS attach pieces

C=Chris Heintz says aint rocket science.

Thus D=put it somehwere between the two points and you will be OK.


Personally I placed it just a hairs distance behind the aft bulkhead.


Good luck,


Dave Gallagher (camped out 3000 miles from my airplane so I can't fly)


P.S. I had to drop my HS leading edge down a handful of degrees to get my elevator trim forces where I liked them.
